无法创建车把模板

Question

我有一个带有JSON对象的车把模板。

处理条形码-

<script id="list" type="x-handlebars-template">
{{#each items}} {{! Each item is an "li" }}
<li>
    {{label}} :
    {{value}}
    {{#if items}}
    <ul>
    {{> list}} {{! Recursively render the partial }}
    </ul>
    {{/if}}
</li>
{{/each}}

<script id="main" type="x-handlebars-template">
    <ul>
        {{> list}}
    </ul>
</script>

JSON对象为-

var items =[
  { "label": "TotalRented", "value": "5" },
  { "label": "AncilleryItems", "items": [
    { "label": "Item", "value": "CarSeat" },
    { "label": "Qty", "value": "2" },
    { "label": "Cost","items": [
          { "label": "VAT", "value": "$20" },
          { "label": "Total", "value": "$100" }
      ]
    },
    { "label": "Item", "value": "GPS" },
    { "label": "Qty", "value": "1" },
    { "label": "Cost", "items": [
          { "label": "VAT", "value": "$10" },
          { "label": "Total", "value": "$50" }
      ]
    }
  ]
  },
  { "label": "Colour", "value": "red" }
 ];

// The main template.
var main = Handlebars.compile( $( "#main" ).html() );

// Register the list partial that "main" uses.
Handlebars.registerPartial( "list", $( "#list" ).html() );

// Render the list.
$( "body" ).html( main( { items: items } ) );

像小提琴一样，此代码将为我正确呈现树结构数据-http: //jsfiddle.net/achyut/V6HNd/1/

现在，我的JSON对象已更改，并且现在有了额外的方括号，用于逻辑分隔。 我现在无法使用额外的括号来渲染树结构。 任何人都可以告诉需要在车把模板中更改哪些代码。

新的JSON对象是

var items = [
  { "label": "TotalRented", "value": "5" },
  { "label": "AncilleryItems", "items": [
  [
    { "label": "Item", "value": "CarSeat" },
    { "label": "Qty", "value": "2" },
    { "label": "Cost","items": [
        [
          { "label": "VAT", "value": "$20" },
          { "label": "Total", "value": "$100" }
        ]
      ]
    }
  ],
  [
    { "label": "Item", "value": "GPS" },
    { "label": "Qty", "value": "1" },
    { "label": "Cost", "items": [
        [
          { "label": "VAT", "value": "$10" },
          { "label": "Total", "value": "$50" }
        ]
      ]
    }
  ]
 ]
},
{ "label": "Colour", "value": "red" }
]

由于您具有项目数组，因此必须再次循环它并访问对象，您可以使用this

{{#each items}} 
   {{#each this}} {{! Each item is an "li" }}

     {{! Code here }}

   {{/each}}
{{/each}}
